Aquarium Auto Top Offs

Aquarium auto top-offs (ATOs) are devices that automatically replace evaporated water in aquariums, maintaining stable water levels and preventing overheating [4]. Here are some key points about ATOs:

· Types of ATOs: There are two main types: float switch ATOs and optical sensor ATOs [4]. Float switch ATOs use a floating switch to trigger water addition, while optical sensor ATOs use a light beam to detect water level changes.

· Benefits: ATOs prevent overheating, reduce manual maintenance, and maintain stable water parameters [4].

· Popular brands: Some popular ATO brands include Tuning Valve, Octo, and AquaTop [5].

· Installation: ATOs are typically easy to install and can be placed in various locations, such as near the aquarium or under the tank [4].

· Adjustability: Many ATOs are adjustable, allowing you to customize the frequency and amount of water added [4].

By using an ATO, you can enjoy a more stable and healthy aquarium environment with less manual maintenance.
